Run hard, whats that. It is drivin . The vehicle takes my scooters out by my brothers' kids for a blast. That is about 100 miles round trip. It does burnouts and the wide open downshifts that kick nice. Using a phone device with GPS an app for testng performance, claimed sub 16 quarter at 88 mph. To take it to a track is big money, and all the test and tune days are gone. Byron, Rt 66 ,and great lakes are busy, and have no time for my messing around. For the admit you might get 2-3 runs. This has been together many months.

The keeper/locks are stock from the vortec 906 heads. If someone works at a yard or parts depot, measure the v6 series 2 valves, that will tell if it is really 8mm or 11/32 .
